European stocks were mostly stable on Tuesday as investors remained cautious amid escalating tensions in the Middle East and as the deadline set by U.S. President Donald Trump for Iran to reach a deal approached. The banking sector led gains, rising 0.7%, while the information technology sector saw the smallest increase. Major European stock exchanges were stable or saw slight gains: Germany's DAX index fell 0.1%, while London's FTSE 100 index rose 0.1%. The European Stoxx 600 index rose 0.1% to 597.24 points. The rise in the banking sector came as trading resumed in Europe after a long holiday for Easter. ASM shares fell 4.2%.
